Open a terminal and cd to the directory with the folders. Then run the following command:
for /f "tokens=* usebackq" %G in (dir /b /a:d "%cd%") do "c:\Program Files\7-Zip\7z.exe" a -r -tzip "%~G.zip" "%~G
Make sure you have 7z installed under default installation target. Otherwise it won’t find the 7z.exe.
Getting an epson pos printer up and running under linux is very easy:
# add current user to lp group (requires relogin to work properly)
sudo usermod -a -G lp $USER
# for TM-T20II add udev rule (optional in my case):
echo 'SUBSYSTEM=="usb", ATTRS{idVendor}=="04b8", ATTRS{idProduct}=="0e15", MODE="0664", GROUP="lp"' > sudo tee -a /etc/udev/rules.d/99-escpos.rules
sudo service udev restart
# install pip and pipenv
sudo apt install python-pip
pip install --user pipenv
# install download python-escpos and submodules
git clone https://github.com/python-escpos/python-escpos.git
cd python-escpo
git submodule update --init --recursive
# install including deps
pipenv install -e .Now you should be ready to use the installation. From your installation repository run a pipenv shell by using “pipenv shell” or simply run “pipenv run python _your-script_.py” to run a script directly.
Here is an example script:
from escpos.printer import Usb
# see https://github.com/python-escpos/python-escpos/blob/development/src/escpos/escpos.py
""" Seiko Epson Corp. Receipt Printer (EPSON TM-T20II) """
p = Usb(0x04b8, 0x0e15, 0, profile="TM-T88II")
p.set(bold=True, underline=1, align='center', custom_size=True, width=2, height=2)
p.textln("Hello world")
p.ln(count=1)
p.set()
p.textln("this is a test")
p.set(align='center')
p.image("examples/graphics/climacons/rain.png")
p.qr("Dies ist ein Test", size=8)
p.set()
p.barcode('1324354657687', 'EAN13', width=3)
p.barcode('123456', 'CODE39', width=3)
p.block_text("Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam nonumy eirmod tempor invidunt ut labore et dolore magna aliquyam erat, sed diam voluptua.

p.cut()After installing redis on my machine I received the following error message:
redis-server.service: Can’t open PID file /var/run/redis/redis-server.pid (yet?) after start: No such file or directory
This message comes because redis refuses to start with disabled ipv6. To get it running you have to remove “::1” from “bind 127.0.0.1 ::1” in /etc/redis/redis.conf. Then redis starts as expected.
This is an example how to do that on a Mac:
|
1 |
sudo keytool -import -noprompt -alias charles-$(date +%Y%m%d%H%M%S) -file "Downloads/charles-ssl-proxying-certificate.pem" -keystore "/Library/Java/JavaVirtualMachines/jdk-10.0.2.jdk/Contents/Home/lib/security/cacerts" -storepass changeit |
First you need to run charles and enable SSL proxying. The see which JDK is used by your application and add the certificate to the cacerts file:
|
1 2 3 4 5 6 |
curl -s http://ssl.charles/ --proxy 127.0.0.1:8888 > cert_file sudo keytool -import -noprompt -alias charles-$(date +%Y%m%d%H%M%S) \ -file cert_file \ -keystore /Library/Java/JavaVirtualMachines/jdk-10.0.2.jdk/Contents/Home/lib/security/cacerts \ -storepass changeit rm cert_file |
Ubuntu
First prepare the ubuntu machine by installing vino:
|
1 |
sudo apt install vino |
Then hit windows button and look for sharing. Configure the system to allow remote connections with given password.
You also need to disable encryption with:
|
1 |
gsettings set org.gnome.Vino require-encryption false |
MAC
Then you can access the machine from your Mac with Screen Sharing app with the url
|
1 |
vnc://<IP>:5900 |
To create a network bridge with netplan you have to create a file
|
1 2 3 4 5 6 7 8 9 10 11 |
network: version: 2 ethernets: enp6s0: dhcp4: true bridges: br0: interfaces: [enp6s0] dhcp4: true optional: false macaddress: <some mac> |
Make sure to place a mac address in and replace the interface name enp6s0 with yours.
Then run sudo netplan apply.
The machine gets a new IP from dhcp so make sure you have it configured in your dhcp before or have a local console 😉
Here a simple docker-compose.yml file to get kong community up and running. It is configured to use postgresql that persists data to a local docker volume. All ports are mapped to localhost only and log goes to stdout/stderr.

Attention: The kong container fails to start unless migrations are not run on the connected database. To do this simply uncomment the marked line and start the containers. With the command set the container will execute database migrations and stop with exit code 0. After that the line can be commented out again. Then you can start kong with the given file.
When using IntelliJ IDEA with Spring Boot on a Mac make sure you have the entry
|
1 |
127.0.0.1 <hostname>.local |
in your /etc/hosts file. Replace <hostname> with your Mac’s name. Also make sure that the result of the command ‘hostname’ is in your /etc/hosts file as well pointing to your local address.
